I did have one waist slip sitting in my drawer for ages, but I tossed it when I realized the elastic waist had disintegrated with age. It had been sitting for a very long time.
I do remember wearing slips in the 70's, but always seeming to wrestle with them because either my pencil skirt had a slit in the back, and the slit in the skirt didn't line up properly, or it was an inch too long, and I had to hike it up and roll it into the waistband of the tights.
The few skirts I have now are either lined, or I wear bare-legged in the summer so don't need a slip.
